It was originally expanded through Swedish mobile phone creator Ericsson in 1994 as a method to let laptop computers make calls above a mobile phone. As then, numerous organizations have signed on to create Bluetooth the low-power thoughtless wireless average for a broad variety of devices (LeVitus, 216-220). Industry spectators anticipate Bluetooth to be fitted in billions of devices through 2005.DiscussionDeveloped by engineers at Ericsson in the late 1990s, Bluetooth is more and more special technology that facilitates thoughtless wireless communication among a diversity of electronic devices. Its mainly important aspect is that it permits devices to “talk” (relocate and orchestrate data) wirelessly with each other, terminating the requirement for the outwardly continuous tangle of cables, cords, and adaptersimportant for numerous today’s expertise.The Bluetooth Special Interest Group (SIG) was formed in 1998 to manage the expansion and prologue of Bluetooth knowledge (LeVitus, 216-220). IBM, Intel, Toshiba and Nokia connected with Ericsson as the beginning associates of the SIG, and in excess of 8,000 organizations have contracted since. So as to trade products with the Bluetooth requirement and logo, manufacturers should be associates of the SIG and the devices should meet well-outlined credentials. These procedures make sure that Bluetooth wireless devices international may converse with each other, apart from company or nation of derivation.Speed and RangeRange is application specific and although a minimum range is mandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling.Range may vary depending on class of radio used in an implementation:∙Class 3 radios – have a range of up to 1 meter or 3 feet∙Class 2 radios – most commonly found in mobile devices , have a range of 10 meters or 33 feet∙Class 1 radios – used primarily in industrial use cases , have a range of 100 meters or 300 feetThat creates Bluetooth technology appropriate for transporting lesser files for example cell phone contracts and text documents, also as lower-quality pictures and audio (Kumkum, 160-162). At these relocate speeds; Bluetooth may not actually deal streaming video or high-quality pictures and audio at this end, except this possibly will alter in the future when fresh Bluetooth standards are initiated.Simple and Competent to UtilizeCreating and configuring Bluetooth allowed devices is moderately uncomplicated, with little extra commotion than acquire the two devices close to one another and twist them on. There is no requirement to mount drivers or further software to complex an ad-hoc, personal wireless network (Kumkum, 160-162). It has a uniform organization, meaning that some two wireless products attributing Bluetooth technology, despite of product or nation of origin, have the ability to converse faultlessly with each other.Common ApplicationsOne of the mainly ordinary applications of Bluetooth is hands-free cell phone procedure. About each cell phone fashioned in our day has constructed Bluetooth (Meier, 15-20). Only pair phone with a Bluetooth headset, and he may talk whereas his phone is in his purse or pocket. Several of today’s car stereos as w ell have fitted Bluetooth for hands-free calling in his vehicle. And if his vehicle has a plant stereo or grown-upaftermarket one that he merely doesn’t wish to restore, he may yet like hands-free identifying with a Bluetooth car kit.BluetoothBluetooth is the fresh Bluetooth wireless typical adopted through the Bluetooth SIG on April 21, 2020. The fresh standard supports elevated data remove speeds and constructs ahead the preceding standards (Meier, 15-20). With its superior speed, the technology has the probable to transfigure the consumer electronics industry.PROTOCOLThe Bluetooth technology standard is set to make different applications can “communicate” with each other. Remote devices in communication use the same protocol stacks, while different applications need different protocol stacks. But, every application needs the data link layer and physical layer of the Bluetooth technology. The whole Bluetooth protocol stacks is shown as blow. Not any application should use all of the protocols, but one or some lists of these. The chart below shows the relationship between protocols, but the relationship may change in some applications.The completely protocol stacks include Bluetooth special protocols (like LMP and L2CAP) and not special ones (such as OBEX and UDP). The basic principle for designing protocol and protocol stacks is that use existing high level protocol as possible, ensure the combination ofprotocols and Bluetooth technology, and take the best advantage of the software and hardware which adapt to the Bluetooth technology standards. The open Bluetooth technology makes device manufacturers can choose protocols freely as they like or used to.The protocols in Bluetooth protocol systemThere are four layers in Bluetooth protocol system according to the SIG∙Core protocols∙Cable replacement protocols∙Telephony control protocols∙Adopted protocolsExcept the protocol layers above, the standard also defines Host/Controller Interface (HCI),which provides command interface for baseband controller, connection manager, hardware state and control register.Bluetooth core protocols consist of the special protocols made by SIG. Most Bluetooth devices need core protocols, while other protocols are used depend on needs of the application. After all, cable replacement protocols, technology control protocols and adopted protocols based on the core protocols constitute the object-oriented protocols.∙Core protocols∙LMP (Link Management Protocol)Used for control of the radio link between two devices. Implemented on the controllers. It identifies and encrypts through launching, exchanging and checking the connection, and decides the size of baseband data packets through conference. It also controls the power mode and work cycle of wireless equipment, and connection status of unit equipment in piconet.∙L2CAP (Logical Link Control & Adaptation Protocol)This protocol is used to multiplex multiple logical connections between two devices using different higher level protocols, and provides segmentation and reassembly of on-air packets.In Basic mode, L2CAP provides packets with a payload configurable up to 64kB, supported MTU.In Retransmission & Flow Control modes, L2CAP can be configured for reliable or isochronous data per channel by performing retransmissions and CRC checks. Bluetooth Core Specification Addendum 1 adds two additional L2CAP modes to the core specification. These modes effectively deprecate original Retransmission and Flow Control modes:∙Enhanced Retransmission Mode (ERTM): This mode is an improved version of the original retransmission mode. This mode provides a reliable L2CAP channel.∙Streaming Mode (SM): This is a very simple mode, with noretransmission or flow control. This mode provides an unreliable L2CAP channel.Reliability in any of these modes is optionally and/or additionally guaranteed by the lower layer Bluetooth BDR/EDR air interface by configuring the number of retransmissions and flush timeout (time after which the radio will flush packets). In-order sequencing is guaranteed by the lower layer.Only L2CAP channels configured in ERTM or SM may be operated over AMP logical links.∙SDP (Service Discovery Protocol)Service Discovery Protocol (SDP) allows a device to discover services supported by other devices, and their associated parameters. For example, when connecting a mobile phone to a Bluetooth headset, SDP will be used for determining which multiplexer settings needed to connect to each of them. Each service is identified profiles) assigned a short form UUID (16 bits rather than the full 128)/vichitra∙Cable replacement protocols(RFCOMM)Radio frequency communications (RFCOMM) is a cable replacement protocol used to create a virtual serial data stream. RFCOMM provides for binary data transport and layer.RFCOMM provides a simple reliable data stream to the user, similar to TCP. It is used directly by many telephony related profiles as a carrierfor AT commands, as well as being a transport layer for OBEX over Bluetooth.∙Telephony control protocols (TCP).Telephony control protocol-binary (TCS BIN) is the bit-oriented protocol that defines the call control signaling for the establishment of voice and data calls between Bluetooth devices. Additionally, "TCS BIN defines mobility management procedures for handling groups of Bluetooth TCS devices."TCS-BIN is only used by the cordless telephony profile, which failed to attract implementers. As such it is only of historical interest.∙Adopted protocolsAdopted protocols are defined by other standards-making organizations and incorporated into Bluetooth’s protocol stack, allowing Bluetooth to create protocols only when necessary. The adopted protocols include:∙Point-to-Point Protocol (PPP): Internet standard protocol for transporting IP datagrams over a point-to-point link.∙TCP/IP/UDP: For communicating with the device connected to Internet. ∙Object Exchange Protocol (OBEX): Session-layer protocol for the exchange of objects, providing a model for object and operation representation. It uses the client-server mode.∙Wireless Application Environment/Wireless Application Protocol(W AE/W AP):W AE specifies an application framework for wireless devices and W AP is an open standard to provide mobile users access to telephony and information services.SPECTRUM AND INTERFERENCEBluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at to GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. The GHz ISM band is available and unlicensed in most countries.SIM frequency band is open to all radio system, So the use of a certain frequency band will meet unpredictable interference sources. Therefore, Bluetooth designs special fast acknowledge and frequency hopping technique to ensure the stability of link. Frequency hopping technique to divide the band into many frequency hopping channels, in a connection, radio transceiver “jump” from a channel to another constantly according to certain code sequence. Only sender and receiver communicate according to this law, and the rest of interference may not press the same rule. The instantaneous bandwidth of Frequency hopping is very narrow, but through the spread spectrum technology it can make the narrow bandwidth one hundred times expanded into wideband, making the influence of interference may become very small. Comparing to other systems that work in the same frequency band, frequency hopping of Bluetooth works faster, data packet of Bluetooth is shorter,which make it more stable than the other.ERROR CORRECTIONBluetooth supports circuit switching and packet switching two techniques, and defines two types of link connection, namely connection-oriented synchronous link (SCO) and connectionless-oriented asynchronous link (ACL)Bluetooth use three error correction models: 1/3 Forward Error Correction (FEC), 2/3forward Forward Error Correction and Automatic Repeat Request (ARQ). Purpose to the error correction is to reduce the possibility of retransmission, while at the same time increase the extra expenses, but in a reasonable errorless environment, redundant bids will reduce output. So the packet definition itself also keeps flexible ways. Hence the software can be defined whether to adopt FEC. In general, when the channel noise is large, Bluetooth system will uses FEC, in order to ensure the quality of communication: as to SCO link, 1/3 FEC is used; 2/3 FEC is used in ACL link. In unnumbered ARQ, the data send in a time slot must receive a confirmation of receipt in the next time slot. Only when the data is checked to be without mistake after header error detection and CRC at receiver will the confirmation sent to sender, or an error message will be sent back.RANGERange is application specific and although a minimum range ismandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling.Range may vary depending on class of radio used in an implementation:∙Class 3 radios – have a range of up to 1 meter or 3 feet∙Class 2 radios – most commonly found in mobile devices , have a range of 10 meters or 33 feet∙Class 1 radios – used primarily in industrial use cases , have a range of 100 meters or 300 feetPOWERIn order to make a Bluetooth equipment can also be in connection even in a very low power state, Bluetooth stipulates three energy saving state: Park state, Hold state and Sniff state. The energy saving efficiency of these states declines one by one.The most commonly used radio is Class 2 and users of power. Bluetooth technology is designed to have very low power consumption. This is reinforced in the specification by allowing radios to be powered down when inactive.The Generic Alternate MAC/PHY in Version HS enables the discovery of remote AMPs for high speed devices and tums on the radio only when needed for data transfer giving a power optimization benefit aswell as aiding in the security of the radios.Bluetooth low energy technology, optimized for devices requiring maximum battery life instead of a high data transfer rate, consumers between 1/2 and 1/100 the power of classic Bluetooth technology.SECURITYMobility and open of Bluetooth system makes safety problems extremely important. Although the frequency modulation technique used by Bluetooth system has already provided a certain security, but Bluetooth system still need safety management to link layer and application layer. In link layer, Bluetooth system provides authentication, encryption and key management, and other functions. Each user has a Personal Identification Number (PIN), which will be translated into 128 bit link key for one-way or both-way certification. Once the authentication finished, link will use encryphon key to encrypt. The link layer security mechanism provides a great deal of certification schemes and a flexible encryption scheme (means allow the consultation of the length of password). This mechanism is very important when the equipments in communication are from different countries, because some countries will specify maximum password length. Bluetooth system will select the smallest maximum allowable password length of all equipments in the piconet.Bluetooth system also supports the high level of protocol stack indifferent applications of special security mechanisms. Bluetooth security mechanism builds trust relationship between devices relying on pins. Once this relationship established, these pins can be stored in the equipment, in order to connection more quickly the next time.中文译文蓝牙技术卡尔·尼伯尔引言蓝牙是永久性的，有限的无线电连接，驻留在微芯片上。

藍芽Bluetooth"藍芽" 名稱源起“藍芽” 是由一位丹麥國王，名叫Harald Blatand 的維京人所命名的。

Blatand 可以被解釋為“Bluetooth(藍芽)”。

但是，為什麼一位古代國王的名字會和無線技術有所關聯呢？他們之間可能沒有什麼關係，但是有這麼一個有趣的來源說法：Harald Blatand 統一了丹麥及挪威，就如同無線技術串聯了人們彼此。

藍芽組織在1998 年 5 月，Intel、Ericsson、Nokia、IBM 及Toshiba 成立了Special Interest Group，名為SIG，其目的為建立一種短距離的無線電頻率無線技術。

到了1999 年 6 月，SIG 的成員增加為751 個，其中包含了Compaq、Dell、Motorola、3Com、HP、Lucent 及Samsung，同時彼此間也達成共識制訂標準化以降低技術成本，讓此技術能被更廣泛地運用。

什麼是藍芽？藍芽是一種無線傳輸的技術，可以讓桌上及膝型電腦、個人數位助理(PDA)、行動電話、印表機、掃瞄器、數位相機，甚至是家電用品之間進行短距離的無線連結。

藍芽(晶片組)的原理就是在ISM 頻帶的頻率中傳輸資料及語音。

每一種具備藍芽技術的裝置皆擁有標準的位址，可以讓您使用低功率的無線電進行一對一或一對七(形成一個小型的網路)的連結，傳輸範圍最遠可達10 公尺(接下來為100 公尺)。

藍芽不僅具有每秒1MB 的高傳輸率，同時也可以使用pin 碼進行加密編碼。

由於具備每秒1600 hop 的hopping 率，因此很難被電磁波攔截及阻斷。

藍芽技術於日常生活影響深遠藍芽技術（Blue Tooth）是新一代無線連結科技，也是通行全球的無線連結標準，由於是使用成本低功率的無線電傳輸技術，讓不同產品(例如印表機、PDA、PC、傳真機、鍵盤、Notebook)於短距離進行資料傳輸及溝通，因此藍芽不必使用任何有線的傳輸線路(例如電線或纜線)，就能連接各種數位設備，讓所謂的行動通訊美夢成真。

蓝牙(bluetooth)技术概述1998年5月，五家世界著名的大公司－－爱立信（Ericsson）、诺基亚（Nokia）、东芝（Toshiba）、国际商用机器公司（IBM）和英特尔（Intel）联手推出了蓝牙(Bluetooth)计划。

这五家公司包含了两家著名的移动通信制造公司、两家著名的便携式计算机制造公司和一家在芯片技术和数字信号处理（DSP）技术上领先的公司。

这项计划公布后，迅速得到包括摩托罗拉、朗讯、康柏、西门子、高通、3Com、TDK等大公司在内的许多厂商的支持和采纳。

第一批应用“蓝牙”技术装备的产品，包括手机、电话机和便携式计算机等，在1999年的年底纷纷进入市场。

要了解蓝牙技术的原理及发展前景，首先要弄清楚什么是蓝牙！一、什么是蓝牙· 蓝牙(B1uetooth)含义：狼的牙齿参差不齐，却能紧紧地啮合在一起，这种设备同样会让耳机、笔记本电脑、冰箱等毫不相关的产品紧密结合在一起。

由于狼牙在月光下会发出蓝光，“蓝牙”由此得名。

· 蓝牙技术实质：一种短距离无线通信标准二、Bluetooth系统的组成蓝牙系统由天线单元、链路控制（固件）单元、链路管理（软件）单元和蓝牙软件（协议栈）单元四个功能单元组成。

１．天线单元蓝牙要求其天线部分体积十分小巧、重量轻，因此，蓝牙天线属于微带天线。

２．链路控制（固件）单元在目前蓝牙产品中，人们使用了３个IC分别作为联接控制器、基带处理器以及射频传输／接收器，此外还使用了３０～５０个单独调谐元件。

３．链路管理（软件）单元链路管理（LM）软件模块携带了链路的数据设置、鉴权、链路硬件配置和其它一些协议。

LM能够发现其它远端LM并通过LMP（键路管理协议）与之通信。

４．软件（协议栈）单元蓝牙的软件（协议栈）单元是一个独立的操作系统，不与任何操作系统捆绑。

它必须符合已经制定好的蓝牙规范。

蓝牙规范是为个人区域内的无线通信制定的协议，它包括两部分：第一部分为核心（Core）部分，用以规定诸如射频、基带、连接管理、业务搜寻（service discovery）、传输层以及与不同通信协议间的互用、互操作性等组件；第二部分为协议子集（Profile）部分，用以规定不同蓝牙应用（也称使用模式）所需的协议和过程。

bluetooth单词1. 定义与释义单词：bluetooth1.1词性：名词1.2中文释义：蓝牙，一种短距离无线通信技术标准。

1.3英文释义：A short - range wirelessmunication technology standard.1.4相关词汇：bluetooth - enabled（形容词，蓝牙功能的），bluetooth device（名词，蓝牙设备）。

---2 起源与背景2.1词源：“Bluetooth”这个名字源于10世纪的丹麦国王哈拉尔德·蓝牙（Harald Bluetooth）。

据说，他统一了丹麦和挪威，就如同蓝牙技术统一了不同的设备通信一样。

2.2趣闻：蓝牙技术的标志是由北欧古字母中的H和B组成，这两个字母正是哈拉尔德·蓝牙名字的首字母。

---3 常用搭配与短语3.1短语：（1）bluetooth headset：蓝牙耳机例句：I use a bluetooth headset to listen to music when I'm on the go.翻译：我在外出时使用蓝牙耳机听音乐。

（2）bluetooth connection：蓝牙连接例句：The bluetooth connection between my phone and the speaker is very stable.翻译：我手机和音箱之间的蓝牙连接非常稳定。

（3）bluetooth pairing：蓝牙配对例句：I had some trouble with the bluetooth pairing of my new device.翻译：我的新设备蓝牙配对时遇到了些麻烦。

---4 实用片段（1）. "My bluetooth speaker won't connect to my phone. I've tried everything!" Tomplained to his friend. His friend replied, "Maybe you should restart both the speaker and your phone and then try the bluetooth connection again."翻译：“我的蓝牙音箱连不上我的手机了。

信息技术英文缩写与解释Company number：【WTUT-WT88Y-W8BBGB-BWYTT-19998】AVI 影音文件 Audio Video Interleaved声音图象交叉存取。

AVI是一种微软媒体文件格式，类似于MPEG和QuickTime。

在AVI中，声音和图象是交叉的存取在一个文件中的每个段的。

ADSL 非对称数字用户线路非对称数字用户线路。

这种DSL叫做非对称DSL，将成为广大家庭和小型商业客户最熟悉的一种DSL。

ADSL之所以叫做非对称是因为它的两个双工通道都用来向用户传输数据。

仅有很小一部分带宽用来回送用户的信息。

然而，大部Internet 特别是富于图形和多媒体Web 数据需要很大的下传带宽，同时用户信息相对比较少，上传的带宽也不要很大。

使用ADSL时，下传的速率可以达到 Mbps，而上传速率也可以达到640 Kbps。

高的下传速率意味着您的电话可以传输动画，声音和立体图形。

另外，一小部分的带宽可以用来传输语音信号，您可以同时打电话而不用再使用第二条电话线。

不象电视线路提供的相同的服务，使用ADSL，您不需要和您的邻居争用带宽。

有时候，现有的电话线可以使用ADSL，而有时候却要升级，除非电话公司提供了无分离器的ADSL，您就必须安装一个DSL调制解调器。

ASP (Application Services Provider) 应用服务提供商是指配置、租赁、管理应用解决方案，它是随着外包趋势、软件应用服务和相关业务的发展而逐渐形成的。

ASP具有三大特点：首先，ASP向用户提供的服务应用系统本身的所有权属ASP，用户租用服务之后对应用系统拥有使用权；并且，应用系统被集中放置在ASP的IDC（Internet数据服务中心）中，具有充足的带宽、电力和空间保证以及具有专业质量的系统维护服务；ASP定期向用户收取服务费。

应用服务提供商将以全新的方式推动应用服务产业的巨大发展。

ATM (Asynchronous Transmission Mode) 异步传输模式这是为满足宽带综合业务数据通信，在分组交换技术的基础上迅速发展起来的通信新技术。

什么是蓝牙(Bluetooth)？一、蓝牙名字的由来蓝牙的名字来源于10世纪丹麦国王Harald Blatand－英译为Harold Bluetooth。

在行业协会筹备阶段,需要一个极具有表现力的名字来命名这项高新技术。

行业组织人员，在经过一夜关于欧洲历史和未来无限技术发展的讨论后，有些人认为用Blatand国王的名字命名再合适不过了。

Blatand国王将现在的挪威，瑞典和丹麦统一起来；就如同这项即将面世的技术，技术将被定义为允许不同工业领域之间的协调工作，例如计算，手机和汽车行业之间的工作。

名字于是就这么定下来了。

在丹麦的Jelling城，在教堂里立着一块纪念碑，这块纪念碑就是为了纪念Blatand国王的功绩和他的父亲,丹麦的第一个国王“Gorm the Old”而立的。

有趣的是，这块特别的石头在Harald和他的儿子Sven Forkbeard之间的一次战争后就遗失了，近600年里没有人见过这块石头。

Sven获胜了（并且把他父亲流放了），因为这块刻着古代北欧文字的石头是Harald的荣耀，所以Sven埋葬了它。

直到最近几年，一个农夫对他农场里的这个大土堆产生了好奇，才终于发现了这块石头。

这个标志最初是在商业协会宣布成立的时候由Scandinavian公司设计的。

标志保留了它名字的传统特色，包含了古北欧字母“H”，看上去非常类似一个星号和一个“B”，在标志上仔细看两者都能看到。

二、蓝牙技术介绍“蓝牙”（Bluetooth）原是十世纪统一了丹麦的国王的名字，现取其“统一”的含义，用来命名意在统一无线局域网通讯标准的蓝牙技术。

蓝牙技术是爱立信、IBM等5家公司在1998年联合推出的一项无线网络技术。

随后成立的蓝牙技术特殊兴趣组织（SIG）来负责该技术的开发和技术协议的制定，如今全世界已有1800多家公司加盟该组织，最近微软公司也正式加盟并成为SIG组织的领导成员之一。

蓝牙是无线数据和语音传输的开放式标准，它将各种通信设备、计算机及其终端设备、各种数字数据系统、甚至家用电器采用无线方式联接起来。
